Silverlight Salmagundi

Here’s a salmagundi of information and links covering the just-released Beta of the up-and-coming Silverlight 4.

(In case you were wondering, I’m using the term salmagundi to refer to a mishmash of little things. A salmagundi is an salad dish dating back to England in the 1600s made of meat, seafood, vegetables, fruit, leaves, nuts and flowers.)

What’s New in Silverlight 4 Beta?

The short answer is: a lot. The long answer is provided by Tim Heuer (one of the program managers for Silverlight), who’s written a blog article titled Silverlight 4 Beta – A Guide to the New Features, which are:

The Tools You Need

 A set of wrenches in various sizes.

Here’s a quick list of what you need to get started with developing with Silverlight 4 Beta.



  • Windows and Mac Developer Runtimes. If you installed the Silverlight 4 Beta Tools for Visual Studio 2010 above, you’ll have the Windows runtime. These runtimes are for test machines. Please note that these are developer runtimes – there aren’t any ready-for-average-user-consumption Silverlight 4 runtimes yet!
  • Microsoft Expression Blend for .NET 4 Preview. If you’re serious about building user interfaces with Silverlight 4 (and WPF 4, if you’re using the full-on Visual Studio 2010 Beta or Visual C# Express 2010), you’ll want to use Blend in conjunction with Visual Studio 2010/Visual Web Developer Express.
  • Silverlight Toolkit. This provides additional open source controls for Silverlight applications.
  • WCF RIA Services. These simplify building n-tier apps by pairing ASP.NET on the server side with client-side Silverlight. They provide a pattern in which you write application logic running on the mid-tier, control access to data, and end-to-end support for common tasks like data validation, authentication and roles using ASPNET’s services.

Silverlight’s Commitment to the Mac

The org chart at The Empire describes Jesse Liberty as the Senior Program Manager of the Silverlight Development Team, but both his business card and he himself will tell you that his title is “Silverlight Geek”. No matter which title you choose, it’s clear that he is the keeper of the Silverlight flame.

In a recent entry on his blog, he wrote:

When I joined Microsoft and started talking about Silverlight, many in the Mac community expressed skepticism about Microsoft’s long-term commitment to the Mac platform. In its most rabid form, the concern was that we were supporting the Mac only preemptively and would drop our support for the Mac as soon as enough Mac developers embraced it (!)

So, 2.5 years later, with the worst not having happened, I have renewed my personal pledge to make sure, to the best of my ability, that Silverlight not only continues to work on the Mac but looks and feels like a Mac app.

And what’s his machine? It’s a MacBook Pro, running both Windows 7 and Snow Leopard, hooked to a 24” Cinema Display. He writes:

I absolutely understand company loyalty (and loving the Mac is not disloyal to Microsoft) but I tend to believe that we do best in recognizing the strengths of our allies and our competition.
